Ageing: A Biophysiological Manifestation
In life, there is only one eternal truth, i.e. once a person is born, he/she has to die. This can occur at any age due to disease, accident or any other cause. We will refer to a person ‘old’ at the age of 65 years and onwards for our discussion.
Ageing and ‘old’ age
Normal ageing individual’s experiences are not necessarily harmful. The ageing process happens during an individual’s lifespan. We all are involved in this process, and none can escape it.
When one is young ageing is associated with growth, maturation and development. Many human abilities peak before the age of 30, while other skills continue to grow throughout life.
A vast majority of individuals over the age of 65 today are happy, healthy, and fully independent.
Despite this, some individuals begin to undergo changes that are known as signs of deterioration or decline.
The changes that are experienced by ageing individuals are not necessarily harmful. With age hair thins and turns grey, skin thins; becomes less elastic and sags, showing wrinkles.
There is a slowing down of functions that go forward throughout adulthood, resulting in loss of functions of body organs.
In the gastrointestinal system, for example, production of digestive enzymes diminishes, thus reducing the body’s ability to break down the ingested food materials.
These changes may not be noticeable until later life. Based on the same theory eyesight and hearing may also be affected. The arteries stiffen with age and are associated with fatty deposits leading to hardening of arteries.
Similar changes can take place in the heart muscles reducing the individual’s heart pumping action resulting body’s ability to retrieve oxygen from the blood.
Similar changes result in less oxygen supply to the brain and may damage and reduce the functional ability of the affected cells.
In the lungs, the tissues begin to lose their elasticity and affects the maximum breathing capacity (vital capacity) and gaseous exchange.
Other Changes In Body
Other noticeable changes are in the Kidneys, different metabolisms, muscle atrophy, and weakness. Brain cells are susceptible and losing some streaks of connective tissue may result in the dullness of the mind and activity.
Hormones play a crucial role in an individual’s sexual health. As the age advances, women go through Menopause with both mental and physical changes whereas in men, sperm production decreases and prostate enlarges, causing increased frequency of urination.
One of the most common changes in the ageing process is osteoporosis and demineralization of bones. The process decreases the absolute amount of bone mass.
This is by far the most typical form of bony change prevalent in aged people leading to fractures following minimal trauma. Age-related bone loss is greatly accelerated in women after the onset of menopause.
Fractures of the wrist bones, hip joints (neck of the femur) and vertebral columns are all related to osteoporosis. Another important manifestation of the old age is a gradual and progressive onset of osteoarthritis due to the ageing of the bones and joints cartilages’ making the movements restricted and painful.
The ageing process also brings social and emotional changes and loss into our lives. Inevitably as we age, older relatives die, then some of our friends may grow frail and die. Loss of spouse at old age affects many.
Nowadays, with the concept of nano families and opening up of many intercontinental job availabilities, families are faced with harsh realities. One will find that children are going away and working outside their own homes, and many of them are settled in different cities and countries.
Old parents though happy otherwise for the children’s achievements, feel lonely and miss their children/grandchildren. Under any of the above circumstances, the old and the fragile parents develop a sense of insecurity and often go into depression
Following are the customary precautions that should be taken by a senior citizen:-
- A disciplined life with proper food habits.
- Avoid greasy/fatty food.
- Do not overeat.
- Indulge in routine exercises like walking in a park and practice yoga routine.
- Ensure regular intake of vitamins and antioxidants.
- Avoid anger and do what brings you and your companion happiness and satisfaction.
- Maintain a stable financial status with an extra amount for unforeseen emergencies and rainy weather.
- Be social and helpful.
- Follow medical advice ardently and religiously. Do not skip essential medicines prescribed by your family doctor.
Be a Boon and Not a Bane to the Society
It is correctly said, “You are only as old as you think you are.” Growing older carries with it some natural changes – like those creaky knees, diabetes, chronic harassing cough with sinusitis, frequent nocturnal visits to the toilet, etc.
But folks who see good years ahead and who don’t accept stereotypes of ageing such as ‘YOU’ are a boon and not a bane to the society and may live longer.
Rather than thinking about mundane things such as low/high BP and cholesterol if you can see the glass half full and refillable instead of half-empty, it could play an even bigger role in living a better, longer and productive life.
Extensive researches on such action have shown an increase in lifespan by about four years.
We must seek to ignore the stereotypes and look at other individuals as different individuals — each with a distinct set of resources and hurdles to his credit.
I must congratulate, ‘Biolir Chora’ for offering such a platform and a plethora of opportunities to showcase our capabilities.
So be happy and be content with whatever you have got and keep yourself happy and blessed. Enjoy every day of your life that God has given you as a bonus.
Remember as Bollywood guys say it…‘Zindagi Na Milegi Dobara.’
